EDGE 8, for example, featured the EFM payload, while EDGE 7 returned some "razor-sharp HD near infrared video".

Along the way they've also flown an ArduSat prototype payload, and the recent EDGE 11 mission lifted two payloads provided by South JeffCo (Jefferson County) Robotics, "a highschool robotics club formed via a collaboration of five area high schools".

EDGE 11 was the first flight to launch from Colorado Springs East Airport, after the airport agreed to let the team use its facilities. Here's the field seen from above, shortly after lift-off:

EDGE 11 hit a maximum altitude of 26,690m before coming down some 80km from the launch site. Handily, the landowner was on hand to ferry the pursuit team to the payload on the back of a tractor. Recovery does, though, sometimes requires a bit of a trek, in this case of EDGE 7, some 8km from the nearest road:

Well, it's impressive stuff, and we wish our US cousins all the best in their endeavours. David concluded: "Moving forward, we're focused on getting to the point of collection and publication of our first BEACON dataset. It is exciting for us to be working on an niche area of science -one of the few, we think, still truly open for real, meaningful input from a team of serious amateurs working out of basements, garages, and bedrooms." ®
